ANIMAL-SH EARS.

SPECIFICATION forming part of Letters Patent No. 769,552, dated September 6, 1904.

Application filed April 21, 1904. Serial No. 204,345. (No model.)

Be it known that I, CHARLES h'lAxLovE, residing at New Brighton, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Animal-Shears, of which the following is a specification.

This invention relates to improvements in portable apparatus for clipping sheep and other animals; and it primarily seeks to provide an apparatus of this character of a simple and efficient construction and which can be easily and readily manipulated to serveits intended purposes.

' (nrenerically the invention includes a comb portion carried by a suitable handle and an oscillatory or reciprocal cutter coacting with said comb and driven by suitable motive power through the medium of a rotary shaft and crank connection.

Again, this invention includes an oscillatory wheel which is so arranged as to permit great speed of movement of the oscillatory cutter.

In its more detailed nature the invention consists in certain novel constructions and combination of parts, all of which will be first described in detail and then specifically pointed out in the accompanying drawings, in which Figure 1 is a top plan view of my invention. Fig. is a top plan view thereof. Fig. 3 is a longitudinal section on the line 3 3 of Fig. .1. Fig. -1 is a horizontal section on the line a 1 of Fig. Fig. 5 is a cross-section on the line 5 5 of Fig. 3. Fig. 6 is a detail perspective view of the oscillatory wheel. Fig. 7 is a similar view of the oscillatory arm, together with its cutter-carrying member. Fig. 8 is a similar view of the cutting member detached. Fig. 9 is a top plan view of a slightly-modified form of my invention. Fig. 10 is a longitudinal section thereof on the line 10 10 of Fig. 9.

Referring now to the accompanying drawings, in which like numerals and letters of reference indicate like parts in all the figures, the shears (designated generally by A) consist of a hollow handle 1, in which is mounted a shaft 2, having a crank 2 at one end and an eye or other suitable device (not shown) at the opposite end for connecting with any suitable drive-shaft. (Not shown.) The handle 1 has side flanges 1 and an extension 1, having a semicircular flange 1", to which the base-plate 3, having a circular end 3, is attached by the screw portions :1. or otherwise. At the other end the base-plate 3 has a series of comb-lingers 3 arranged with their points in the arc of a circle.

3 designates a bore in the handle extension 1 to receive a wheel &, hereinafter referred to. Concentric with and of a greater diameter than the bore 3 are countersunk portions 3 3 in the handle extension 1 to form a flange 1, as shown. Held within the coun ter-sunk portion 3 of the extension 1, with its lower face flush with the lower face of the said extension, is a substantially circular plate 5, having a countersunk portion 5 on its upper face to receive a short hub 45 of the oscillatory wheel a, and the said plate 5 has a groove 3 concentric with the portion 5, for the purposes presently to appear.

The wheel has a pair of concentric grooves 1" r of equal radii, one on each face thereof, and the said grooves 1" 4c are of the same radius as the groove 3, so that the said grooves 4:" r 3 are in the same vertical alinemcnt. The wheel 4: has a plurality of transverse apertures +9, communicating with the grooves a" at, and the said wheel also has an extending hub P, having a squared portion a" at its upper end, and the said hub has an elongated bore L, merging with a countersunk portion d to receive the securing-bolt- 6" for a purpose presently explained. Fitted over the wheel a is a circular plate 6, having a concentric bore 6 to receive a hub 4 and a circular groove 6", corresponding with the grooves at? 3, which grooves together form oil-- receiving chambers, the plate 5 having oil-admitting apertures 3'", normally closed by the plugs 3, as shown. The plate 5 and the plate 6 are securely fastened to the flange 1 by the bolts as shown.

7 designates a vibrating arm, including a hub 7, having a semicircular groove 7" to receive the crank 2 of the shaft 2, and the said hub 7 also has a socket '7 to receive the ball connection 8 of the cutter-carrier member 8. The arm 7 also includes a bridge 7, apertured to receive the screw 9, upon which is mounted a check-nut 10, and the said screw 9 has a head 9 and at its lower end terminates in the ball 9 adapted to seat in the socket 8 of the cutter-carrier 8, which carrier 8 passes under the bridge portion '7 and terminates at its forward end in a fork 8", to which the cutter 11 is joined by the screws 11, which pass through apertures 8in the carrier 8. In practice the cutter 11 consists of three cutter-fingers 11 and the comb consists of ten teeth 3", as shown. The arm? has asquared countersunk portion 7 e and threaded bore 7 f to seat the shaft 2 it will cause the arm 7 to vibrate,

thereby imparting a vibratory motion to the wheel 4:, the cutter-carrying member, and the cutter 11.

By providing the wheel 4: and by arranging the cutter-carrying member, the cutter, and the vibrating arm cooperating with the crankarm of the shaft in the manner shown a greater speed of operation can be obtained, the parts moving in the arcs of circles. By constructing the cuttercarrier 'member and arranging it with respect to the vibrating arm, as shown, I insure a more even movement of the cutter and insure its positive contact with the baseplate, and thereby permit the cutter to adapt itself to any unevenness in the surface of contact of the base-plate. By filling the chamber 0 with oil through the oil-apertures in the plate 5 the wheel t wherever it is in movable contact with other parts will always be well lubricated. The desired tension or pressure may be given to the cutter member by simply adjusting the screw 9 in the bridge portion of the vibratory arm. It should be understood that in practice the upper and lower surfaces of the cutter and the upper surfaceof the base-plate where the cutter engages are ground to form a perfect fit, as is also the forked end of the cutter-carrier member.

In Figs. 9 and 10 I have shown a slightlymodified form of my invention in which the arm 7 is of slightly-different form than in the form of my invention shown in Fig. 1, and in this form the hub i is longer than in Fig. 1, and the arm 7 is made substantially rectangular in plan view with the socket 7 c in a plane below the end 7 of the handle opposite the hub 7 and the said end 7 X also has a threaded aperture 7 y to receive the adjustingscrew 9, and in this form the cross portion is eliminated.

In the form shown in Figs. 9 and 10 the cutter-carrier 8 is formed with an enlargement 8', having a bore 8 to permit the end 7" of the arm 7 to pass therethrough, and the said cutter-carrier 8 in this form has its socket so.

arranged as to be in alinement with the adusting-screw 9.

From the foregoing it will be seen that I have provided a simple, durable, and easilyoperated shears which will readily serve its intended purposes, and from the foregoing description, taken in connection with the accompanying drawings, it is thought the complete operation, construction, and advantages of my invention will be readily understood by those skilled in the art to which it appertains.

I desire it understood that slight changes in the detailed arrangement and construction of parts may be made without departing from the scope of the invention or the appended claims.

I am aware that animal-shears have heretofore been provided in which a vibratory motion is given to a cutter through the medium of a rotary shaft and crank connection, and I do not claim such construction broadly; but
